PRODUCT DESCRIPTION
This is a Pre-Filtered Low Noise Amplifier.
Very often signals in the FM band can saturate your receiver and kill the benefit of a Low Noise Amplifier. This module has an integrated FM Notch Pre-filter that will reject strong FM signals and the LNA will amplify Airband, AIS, Weather Band and any other signals all the way up to 3 GHz.
The FM Notch Filter is 7th order. The maximum gain of the LNA is 22 dB.
DC POWER OPTIONS
The module can be powered using any one of three different methods:
1. USB with the use of a Micro USB cable
2. DC header - a wide input voltage range of +4V to +12V DC can be used. Please note that there is no reverse-polarity protection on this device so careful with the + and - terminals
3. Bias Tee - you can solder an inductor onto the provided 0805 footprint and provide DC over the RF output cable
